AUXILIARY HEATER.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed. June 18, 1908. Serial No. 439,127.

T 0 all whom it may concern:

Be it known that I, WILLIAM C. RIOHMAN, a citizen of the United States,residing at Vermilion, in the county of Clay and State of South Dakota,have invented certain new and useful Improvements in AuxiliaryI-Ieaters, of which the following is a specification My inventionrelates to an auxiliary heater or radiator, and consists in theconstruction and arrangement of parts, which will be more fullyhereinafter described illustrated in the drawings, and particularlypointed out in the claims.

The object of my invention is to provide a movable auxiliary heater foruse on coal, oil, gas, gasolene, or alcohol stoves, which shall beadapted to receive and radiate heat; also to provide an auxiliaryradiating heater which shall have great radiating surface and which maybe controlled by a proper damper.

A still further object of my invention is to provide a heater which maybe used on a stove in the parlor or sitting-room, or be carried up andused in an upper room or cham her; and also to provide an auxiliaryheater for people who cannot afford to have stationary heaters such asare generally sold and used, my heater being very cheap of manufactureon account of its simplicity of con struction.

My invention is illustrated in the accompanying drawings forming a partof this application and in which:

Figure 1 is a side elevation of my heater and radiator, as used inconnection with stoves: Fig. 2, is a vertical section of my heater online 38 of Fig. 3-showing a regulator; Fig. 3, is a horizontal sectionof my heater on line 9cx of Fig. 1showing the regulator or damper; Fig.4, is a representation of my heater as used with a stove and in the sameroom, and Fig. 5 is a representation of my heater as used in connectionwith a stove but in an upper room of the house.

It is not essential that my heater shall be used on a stove in preciselythe same manner as shown in Figs. 4 and 5, because I claim this heaterin any of the ways it may be used.

Referring now to the drawings, in which similar letters and numbersindicate corresponding parts throughout the several views: A, representsthe central tube which constitutes the main piece of the heater. Thistube has eight openings 1, preferably of rectangular form cut in itsupper and lower ends to receive the upper and lower ends of the ribbedhollow convolutions 2, which receive the heated air from the tube A,when the damper 3 is turned so as to close said tube. WVhile the heateris in its normal condition with the damper open, the heat will pass upthrough the tube A and out into the room, or may be used to heat thewater in a vessel placed thereon. When the damper 3 is turned so as tocut off the ascent of the heated air, so that said air is forced toascend through the ribbed convolutions 2, the heated air passingtherethrough disseminates and distributes the heat contained in the airtaken from the stove into the air in the room. The tube A may be made ofany desired length and diameter and the ribbed convolutions belengthened in like manner.

3 represents the regulator or damper and is securely fastened. to a rodprovided with a handle and extends across the tube A.

B represents the oil stove which may be of any of the usual styles, andcontrolled by cock or valve.

C shows the oil tank for containing and supplying oil or other fuel,having the usual feed cook or valve.

D is an ordinary coal stove and E the pipe extending therefrom to thechimney.

In Fig. 5 the heater is shown on pipe E, but not in the same room withthe stove, being in fact in the room above.

F is the intervening floor.

Several heaters may be used on one pipe in the same room with the stoveor in several rooms, by merely removing sections of the stove pipe toaccommodate said heater.

This auxiliary heater may be used by placing the same on the top of thestove, or, if desired, within one of the top openings, the lid beingremoved.

Having fully described myinvention and the manner of using the same,what I claim and desire to secure by Letters Patent is:

As an article of manufacture, an auxiliary heater, adapted to be appliedto a stove or other heater, said. auxiliary heater comprising a cylinderor tube, open at its ends, and

In testimony whereof I have affixed my a series of separate chambersarranged signature, 1n presence of tWo wltnesses.

around said tube, said chambers being spaced apart and eXtendin lonitudinally of the tube and communicating therewith WILLIAM RIOHMAN' 5 atboth ends, and a damper mounted in said Witnesses:
